TOBACCO-PIPE AND CIGAR OR CIGARETTE HOLDER.

SPECIFICATION forming part of Letters Patent No. 665,375, dated January 1, 1901.

Application filed December 19, 1898. Serial No. 699,747. (No model.)

- invented certain new and useful Improvements in or Relating to Tobacco-Pipes and Cigar or Cigarette Holders, of which the following is a specification.

This invention has reference-to improvements in tobacco-pipes, cigar or cigarette holders, and to plugs or cores to be placed in a chamber attached to or hollowed out of the stem of same, and has for its object to provide a pipe, cigar or cigarette holder that with the addition of the said plug or core made as hereinafter described and placed in the said chamber will cool the smoke and eliminate from it m uch of the deleterious substances or qualities that in pipes of ordinary construction are drawn into the mouth.

The invention will be fully described with reference to the accompanying drawings, in which- Figure 1 is a partial longitudinal section of a .pipe with my invention applied; Fig. 2, a cross-section through Fig. 1 at a b; Fig. 3, a similar view of a modified form, and Fig. 4 a similar view of a cigar or cigarette holder.

In the drawings like parts are indicated by similar letters of reference, A being the bowl of the pipe, and B the stem or mouthpiece. The part of the pipe 0 between the bowl and stem in Fig. 1 is provided with a chamber D, preferably parallel in the direction of its length and also preferably circular in cross-section, though it will be obvious from what follows that the shape may be varied, the form referred to, however,being considered the best. A passage (1 runs from the bowl into the chamber D, while at the other end the latter is stopped up by the end of the mouthpiece B, which may be screwed into chamber D or merely pushed into it. In Fig. 3 the chamber D is composed of a suitable metallic or like tube E, which may be connected by screwing or the like means both to the bowl A and stem or mouthpiece B. A similar arrangement is adopted in the cigar or cigarette holder shown in Fig. 4:, though the chamber may be formed of Wood, as in Fig. 1. In either case the walls of the chamber are preferably as thin as possible consistent with the strength required, so that the products of combustion in passing therethrough are more or less condensed, owing to the heat readily escaping through the walls. The most important feature of my invention, however, consists in the provision of a loose plug or core F of such a form and character that while allowing the smoke to readily pass from the bowl A to the mouth of the smoker, between its outer surface and the inner surface of the chamber D, will nevertheless absorb the condensed products and prevent their emission from the stem B. The plug is preferably made in the form of a cylinder with projectionsf at the ends to prevent the closing of the passage in the bowl and stem of the pipe or holder, the groove between the projections allowing the smoke to pass when the plug is close up to either the bowl or stem. It will be obvious that the cross-section of the plug and the shape of the projections may be varied.

The core or plug is made of powdered bone or animal charcoal or of a mixture of these and vegetable charcoal-such as that obtained from wood, peat, or grain-to which are added a preferably hot solution of treacle or sugar and borax. I preferably mix the above-named materials together in about the following proportions, viz: five parts of powdered wood charcoal, five parts of powdered animal charcoal, five parts of (preferably) black treacle, and one-half part of powdered boraX. In preparing the mixture the treacle is first heated to boiling-point and the borax added and dissolved therein. The boiling mixture has then added to it the charcoal, the whole forming a spongy, yet loose, mass of such a nature that it can be readily molded and subjected to pressure in suitable apparatus to make it to the forms desired. After molding, the plugs are dried on trays and charred out of contact with the air. Plugs made of the materials described possess very high absorbent properties and are cheap, so that they may be easily renewed, as desired, while they possess sufficient strength to prevent breakage during smoking.

Powdered animal or vegetable charcoal, or both combined and simply made moist by water and pressed together without the addition of any other substance, is of no commercial value in the making of plugs or cores for the purposehereinhefore referred to, since as soon as the pressure is removed and the Water evaporated the particles again crumble and resolve into powder. I therefore employ a material or materials which will cause the charcoal particles not only to adhere, but to impart sulficient strength to enable the plugs or cores to he handled, shipped, and used in tobacco-pipes and yet remain intact,andwh'ile imparting these properties will, on the other hand, interfere as little as possible with the absorptive properties of the charcoal. Black treacle or sugar and borax I have found, after many experiments, to possess these advantages, first, because the treacle or sugar mixed with the charcoal enables the mixture to be readily handled in the operations preparatory to and during molding them under pressure to form them into the shape required, and, secondly, when so molded hold the charcoal particles together d 11 ring the subsequent operations. The borax also gives greater strength to the finished plugs, and the two substances together make a plug' which can also be handled with impunity. These added substances, in addition to the properties named, have such an eliect on the smoke as to neutralize very largely any unpleasant smell or taste caused by such.

I am aware that pounded or granulated charcoal and charcoal alone, formed as a plug or cylinder with a hole passing through its center to enable it to be mounted on and suspended by a central pin or-supporting-piece within the stem or bore of a pipe, has been used prior to the date of my invention, and thatother absorbent materials in different forms have also been used in the stems of pipes for taking up the nicotine. To none of these, however, do I lay claim, and I would have it particularly understood that charcoal in any form by itself, and either of the vegetable or animal variety or both combined, I do not claim as my invention.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. An absorbent plug or core for tobaccopipes, cigar and cigarette holders consisting of a mixture of charcoal, black treacle or sugar, and powdered borax, the whole molded and pressed to form, substantially as described.

2. An absorbent plug or core for tobaccopipes, cigar and cigarette holders consisting of a mixture of vegetable and animal charcoal, black treacle or sugar, and borax, the whole molded and pressed to form, dried and charred, substantially as described.

3. An absorbent plug for tobacco-pipes, cigars and cigarette-holders, consisting of a mixture of charcoal, black treacle, or sugar and borax, molded in the form of a cylindrical body provided with projections at its ends, substantially as described.

at. An absorbent plugfortobacco-pipes, cigar or cigarette holders, consisting of a mixture of charcoal, black treacle or sugar and borax, molded in the form of a cylindrical body of a diameter less than the stem of the pipe, cigar or cigarette holder it is to rest in, substantially as and for the purposes described.

5. The combination with a tobacco-pipe, cigar or cigarette holder provided with a (aha-n1- ber D, of a loose absorbent plug made up of a mixture of charcoal, black treacle or sugar and borax, molded in the form of a cylindrical body of a diameter less than the internal diameter of the chamber D, in the bottom of which it rests, substantially as and for the purposes described.

6. An absorbent plug or core for tobaccopipes, cigar and cigarette holders consisting of substantially five parts of wood charcoal, five parts of animal charcoal, five parts of black treacle, and one-half part. of borax.

In witness whereof I have hereunto set my hand in the presence of two witnesses.
